SPECIFICATION forming part of Letters Patent No. 64:2,195, dated January30, 1900.

Application filed November 18, 1899. Serial No. 737,470. (No model.)

To all whom it may concern:

Be it known that 1, PETER BECKER, a citizen of the United States,residing at 179 Nostrand avenue, borough of Brooklyn, in the city of NewYork, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Apparatus for Making Brushes, ofwhich the following is a specification.

This invention relates to machines for making brushes, its object beingto improve the construction of machines of this character; and with thisobject in view the invention consists of the several details ofconstruction, I 5 combination, and arrangement of parts, as

will be hereinafter more particularly described, reference being had tothe accompanying drawings, in which Figure 1 is a side elevation of amachine constructed in accordance with my invention. Fig. 2 is avertical section on the line 00 so of Fig. 1, part of thesupporting-frame being omitted. Fig. 3 is a plan View, the hopper beingremoved. Fig. at is a plan of the hopper, and Fig. 5 is a sectional viewof the bristleplate and a ring fitted over it for the purpose of moldinga supporting-back about the projecting ends of the bristles.

The supporting-frame consists of a bedplate A, secured to legs a, andthis frame may be of any desired size and height and of any suitablematerial. Secured to the bed-plate and projecting upwardly from it areguidepins 1), preferably one near each corner of the bed-plate, andthese pins serve as guides for a table B in its vertical reciprocation,the table being provided with openings to receive the pins. Secured toand projecting downwardly from the central part of the table is a tongueC, which extends through an opening 0 in the bed-plate, and near itslower end the tongue is provided with a horizontally-extending slot 6,in which a block D is supported to slide horizontally therein. A shaft Eis supported to turn in suitable bearings 7 7, secured to the bed-plateand is provided with fast and loose pulleys 8 and 9 and at its inner endwith a crank e, which works parallel to one face of the tongue 0 and inclose proximity 5o toit. Apin 1O extendsfrom the crank through anopening in the block D, in which opening it fits loosely. A nut 11 orsome similar securing device is attached to the end of the pin toprevent the block D from working out of the slotG. It is obvious thatwhen the shaft E is rotated the tongue 0 and table B will bereciprocated vertically, and the side movement of the crank will betaken up by the sliding of the block D in the slot 6.

The bristle-plates are indicated by F, and these are designed to restside by side upon the table B. Three are indicated in the drawings; butthis number may be increased or diminished, and the holders may be ofany size desired. Each holder is provided with a thickened centralportion f, in which the bristle-receiving holes 1 2 are formed.Preferably these holes will be of uniform diameter throughouttheirlength,butincline outwardly on each side of the middle hole of eachrow, as shown in Figs. 2 and 5.

Some means must be provided to detachably clamp the holders in positionon the table, and preferably I employ two bars G, which are perforatednear their ends to fit over studbolts g, fixed in and projectingupwardly from the table B. These bars when fitted over the bolts 9 willengage the end portions of the holders, and when the nuts 13 aretightened up the holders G will be firmly held in position on the table,but may be quickly removed therefrom when necessary.

The hopper for the bristles consists of a rectangular frame H, in whichare secured two sieves 14 and 15, the former being,in effeet, the bottomof the hopper, and the sides g of the hopper are secured to the frame inany suitable manner and preferably flare outwardly, as shown. The framewill be of sufficient length to extend over all the bristle 9o holdersand of a width to be within the plane of the opposing edges of the barsG in order that the latter may be removed or put into position withoutobstruction by the hopper when the latter is in place. The frame is pro-Vided with horizontally-extending lugs or flanges 1% at each end, whichare perforated, as indicated at 17, to fit over the shouldered andreduced ends 18 of the stud bolts h, which are secured in and project upfrom the :00

table B. The shoulders of the bolts h must be at such height above thetable as to support the hopper-frame G above the top surface of thebristle-holders in order that the latter may be put in position belowthe hopper or removed without necessitating the removal of the hopper.Nuts 19 or similar fastenin g devices will be used to clamp the frame Gon the pins.

The operation of the machine is as follows: Assuming the parts of themachine to be in the position indicated in Fig. 1 and the hop per to besupplied with bristles of a predetermined length, power is applied torotate the shaft E rapidly, and this will result in imparting a quickreciprocating movement to the table B and also the brush-holders andhopper. This movement resultsin violently agitating the bristles, andthey,or rather some of them, assume endwise position and drop downthrough the sieves 14 and 15 into the openings in the brush-holder. Thismovement continues until the holes are filled, when the shaft E isstopped, the bars G removed, and the holders can then be drawn frombeneath the hopper and all the loose bristles brushed off or otherwiseremoved from them. The shaking movement will have caused all orpractically all of the bristles in the holes 12 to engage the table B atone end, while their other ends will project a short distance above theupper surface of the central port-ionf of the bristle-holder, as shownin Fig. 5, where 20 indicates the bristles. It is of course understoodthat the depth of the holes 12 will be equal to the length the bristlesare designed to project from the back of the brush, or substantially so.After being withdrawn from beneath the hopper a mold-ring R is fittedover the raised portion f of the holder, and any suitable plasticcomposition to form a brush-pad is molded about the projecting ends ofthe bristles. When this is set, the bristles can be withdrawn from theholder.

It will of course be necessary to maintain a supporting-surface for theholder and bristles when they are withdrawn from below the hoppers, andfor this purpose the table B may be widened or the holders may beslipped onto a board, as S, andcarried to another table or support forthe purpose of applying the plastic composition. It will thus be seenthat it is not necessary to invert the holders at any time. Q

Having described the invention, I claim 1. In a brush-making machine, asupporting-frame provided with upwardly-extending guide-pins, atablehaving openings to receive said pins and movable vertically thereon,means to impart. a vertical reciprocating movement to the table,brush-holders detachably clamped upon the table and movable therewith,and a bristle-hopper supported by the table and connected thereto tomovewith it and the brush-holders, said hopper having a reticulatedbottom and being supported to leave a space between it and thebrush-holders, for the purpose set forth.

2. In a brush-making machine, a supporting-frame provided with guides, atable movable vertically on said guides, means to impart a verticalreciprocating movement to the .table, brush-holders supported on saidtable,

clam pin g-bars Genga'ging the holders and detachably connected to thetable, stud-bolts h secured to and projecting upwardly from the tableand havingshouldered and reduced ends, a bristle -hopper havingperforated flanges 16 to fit over said reduced ends and rest upon theshoulders, and means to detachably hold the flanges upon the pins,substan-' tially as set forth.

'3. In a brush-making machine, a supporting-frame provided with guides,a table movable vertically on said guides, a bristle-110pper andbristle-holders detachably connected to the table to move uniformly withit, a tongue projecting downwardly from the frame and provided with ahorizontally-extending slot, a perforated block slidably supported inthe slot to move vertically with the tongue but to have independentlateral movement in the slot, a shaft journaled for-rotation in theframe and having a crank adjacent to the tongue, a pin extending fromthe crank and fitting loosely in the block, and means to rotate theshaft, for the purpose set forth. I

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER BECKER.
